Avalanche Forecast
Regions: North Okanagan, Shuswap, South Okanagan.
Up to 15 cm low-density snow fell in the south of the region on Tuesday. Where the wind picks up, fresh wind slabs will form.
Come prepared with lots of warm layers, hot drinks and a headlamp when venturing out. Cold temperatures and short days can turn even small incidents like broken equipment into a very bad time.

Moderate
Avalanche Summary
No avalanches have been reported in this area recently.
If you venture into the backcountry, please submit a MIN report, as it helps to strengthen our data gathering.
Snowpack Summary
Snowpack depths at upper elevations are around 80-110 cm.
Surface: 5-15 cm of recent snow buried previously hard wind-pressed surfaces in the alpine and faceting surfaces in sheltered areas.
Upper-pack: 30 cm of light snow continues to facet with cold temperatures. In exposed areas, you will find a series of old wind slabs and crusts on steep solar slopes.
Mid/lower-pack: A layer of surface hoar, crust, and faceted crystals is buried 50-70 cm deep. Observations are limited in this region, but this layer has produced numerous large avalanches in neighbouring regions. Below this layer, the snowpack is generally weak and faceted.

Terrain and Travel Advice
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for wind slab hazard before you commit to it.
- Use ridges or ribs to avoid areas of wind loaded snow.
Avalanche Problems
Wind Slabs
Up to 15 cm low-density snow fell on Tuesday in the southern part of the region. Where the wind picks up, it will form fresh wind slabs in lee areas near ridge crests and roll-overs.
Recent winds have pressed surfaces and scoured the alpine. Watch for pockets of isolated wind slabs that are reactive to human triggering. Seek out wind-sheltered terrain where you can avoid wind slabs and find great riding.
